I NVENTOR James ATTORNEYZ JAHES X. OMEABA, OF NEW YORK, N. Y.

WINDOW-VENTILATOR.

Specification of Letters Patent.

Patented July 5, 1910.

Application filed August 16, 1908. Serial No. 513,191.

To all whom it may concern:

Be it known that 1, James K. OMnAnA, a. citizen of the United States,and residing at New York, in the county of New York and State of NewYork, have invented certain new and-useful. Improvements in Win-(low-Ventilators, of which the following is a specification, such aswill enable those skilled in the art to which it appertains to make anduse the same.

This invention relates to ventilators for use in Windows; and the objectthereof is to provide an im roved window ventilator which is locate inthe top of a sash, preferably the top sash of the window and which maybe applied to any window sash by simply cutting out the top port1on ofthe glass and placing my improved ventilator in the sash as hereinafterdescribed.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawing forms a part, in which the separate partsof my improvement are designated by suitable reference characters ineach of the views, and in which Figure 1 is an inside view of a window,the top sash of which is provided with my improvement, Fig. 2 a viewsimilar to Fig. 1, but showin only the top portion of a window and t etop portion of the upper sash and showing the method of open n andclosing the ventilator, Fig. 3 a vertica section on the line 3-3 of Fig.2, Fig. 4 a vertical section on the line 4-4 of Fig. 2, and ;-Fig. 5 ahorizontal section on the line 5-5 of Fig. 1, but showing only the sashwith my improvement therein.

In the drawing forming part of this specification, I have shown anordinary window frame comprising a side member a, a top member a and abottom member a, and mounted in the frame is the usual top sash b andbottom sash 0 In the practice of my invention. and in applying the someto an old sash cut out the top portion of the loss 5 horizontally and ata predetermined distance from the top of the sash preferably six oreight. inches and secure in the sash over the glass 6 a horizontal bara. The bar a, the top member b of the sash frame together with the topportions 31* of the sides of the sash form a ventilator frame in the topportion of the sash, and this frame is divided vertically and centrallyby a post or member b which is placed therein as shown in Fig. 5 and asindicated in dotted lines in Fig. 2. This divides the ventilator frameinto two arts (3 and d 111 one of which is placed a g ass 6 and in theother a screen f, and at the front of the glass e and screen 7 I securein the ventilator frame a supplemental frame g which s U-shaped in crosssection as clearly shown in Fig. 5 and preferably composed of sheetmetal and in which is mounted a panel frame It in which is placed aglass h and the panel frame I2. is free to be moved back and forthacross the top portion of the sash in the frame g so as to open or closethe screen f as will be readily understood. It will also be understoodthat the screen f forms the ventilator, and the panel frame it maybemoved so as to entirely close said ventilator or so as to partiallyclose the same or entirely open the same.

In the foregoing description I have described the method of applying myimprovementto an old sash, but it will be understood that the same maybe applied to a new sash by simply placing in the top part thetransverse bar 0, and then placing in the space above said bar the otherparts of my improvement as liereinbefore' described. It will also beapparent that the bottom sash may be provided with a similar ventilatindevice if desired; and changes in and modifications of the constructionherein described may be made, within the scope of the appended claims,without departing from the spirit of my invention or sacrificing itsadvantages.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent, is

I. A window ventilatin device consisting of a bar placed transverse y inone end portion of a sash so as to form an oblong space which extendsentirely across the same between the side frames thereof, a glass placedin one end portion of said space and a screen in the other end portionthereof, and a sliding panel frame provided with a glass and mounted infront of the first named glass and screen and between said bar and thecorresponding end of the and movable transversely of the sash in frontof said glass and screen.

2. A window ventilating device consisting of a bar placed transverselyin one end portion of a sash so as to form an oblong space which extendsentirely across the same between the side frames thereof, and is dividedby a vertical post placed between said bar and the adjacent end of thesash, a glass placed in one end portion of said space and a screen inthe outer end portion thereof, and a sliding panel frame provided with aglass and mounted in front of the first named glass and screen andbetween said bar and the corresponding end of the sash and movabletransversely of the sash.

In testimony that I claim the foregoing 10 as my invention I have signedmy name in presence of the subscmbing witnesses this 2nd day of August1909.
